To: Marcelo Tosatti; +Cc: kvm

the pte accessor names to indicate on which type of pte they operate on.
No functional changes.

To: Marcelo Tosatti; +Cc: kvm
We use shadow_pte and spte inconsistently, switch to the shorter spelling.
Rename set_shadow_pte() to __set_spte() to avoid a conflict with the
existing set_spte(), and to indicate its lowlevelness.
